The information provided on this product is vague and misleading. The 21 inch length referred to includes the two bandsets and the pouch. Each bandset is 9.5 inches long with the small pouch 1.75 inches long x little less than 0.5 inch wide that is meant to accomodate 0.25 inch BBs. The bandsets are tapered from 0.75 inch down to approximately 0.50 in. These bandsets seem fairly powerful and durable and may be suitable for hunting but the pouch will need to be changed to accomodate larger projectiles such as 3/8 in diameter projectiles. The current pouch is more appropriate for target practice using BBs.I will not buy this product again. However, if the bandsets are tapered from 1 in to 3/4 in with a larger pouch (3 in x 3/4 in, say), I will certainly be willing to try out the modified product.I have tested the current bandsets with a 3 in x 3/4 inch pouch with reasonable performance but larger bandsets, I believe, would produce a very competitive product.
